When a single mother returns home with her face bandaged from reconstructive surgery, her twin sons begin to suspect that more than her face has changed—or perhaps the bandaged woman is not their mother, at all.

VICE recently sat down with Goodnight Mommy's two directors—Severin Fiala and Veronika Franz—to talk cockroaches and working with young actors following the film's stateside release.
